ticular requirements,

A link 26 is pivoted to the side of the valve remote from the point Where it is pivoted to the post, and this link in turn is pivotally connected to an operating rod 27 that reciprocates through a guide 28 threaded in the coupling. A collar 29 is adjustably secured on the rod, and a spring 30 encircles the rod and is interposed between the guide 28 and the said collar, acting to force the rod normally outward to hold the valve in engagement with the valve seat of the nipple. The operating rod may be extended to suit parin order that it will terminate within convenient reach of an op- 5 scribed, the horn body 33 will 4 the purpose terminating in a heretofore described. The provision of the erator, and it may be supplied with any suitable handle 31, although I prefer to .have the body in sections with ascrew-joint 13 to permit the body to be separated for of cleaning its interior.

, As the parts are arranged, the valve is held normally closed by the spring 30, and when the operator desires to sound the whistle, he will force the rod inwardly and move the valve and its operating parts to the dotted line positions shown in Fig. 1, or to some modified degree, according tothe amount of noise that is desired, whereas upon release of pressure from the rod, the spring will act to automatically seat the valve. v I

The purpose of the yieldable post is to cause an equalization of the parts so that the valvewill always properly seat when pressure is removed from the rod.

y the collar 29, the tension of the spring may be changed.

' In the modification shown in Fig. 5, the coupling 32 and the interior mechanism and the device foroperating the interior mechanism will be the same as that heretofore described, except that instead of having the nipple on the horn body as heretofore debe connected by an elbow 34 to'the coupling, and the elbow 34: may have a suitable nipple or extension projecting into the coupling 32and valve seat, similar to that modified construction results in permitting the horn to lie horizontally instead of at 'rightangles' to the longitudinal axis of the coupling.

horn body having reason of the adjustment afi'ordedlo} I claim:

1. In an exhaust whistle, a coupling adapted to be inserted in an exhaust line, a nipple threaded in the coupling and having a valve seat on its inner end, a horn body adapted to carry tubes, a yieldable post extending ment with the seat.

2. In an exhaust whistle, a coupling, a horn body having a nipple extending through the coupling, a valve coacting with the end of the nipple to open and close the same, a yieldable post, means for oscillatably mounting the valve on the post, and means connected to the valve for oscillating the valve.

3. In an exhaustwhistle, a coupling, a horn body having a nipple extending through the coupling, a valve coacting with the end of the nipple to open and close the same, a-yieldable post on which oscillatably mounted, means for oscillating the valve, a link connected to the valve, and a rod to which the link is connected and by which the valve is operated.

4. In an exhaust whistle, a coupling, a a nipple extending through the coupling, a valve coacting with the end of the nipple to open and close the same, a yieldable post on which the valve is oscillatably mounted, means for oscillating the valve, a link pivotally connected to the valve, a rod to which the link is pivoted, a guide-carried by rod is slidable, and means rod outwardly.

5. In an exhaust whistle, a coupling, a horn body having a nipple extending through the, coupling, a valve coacting with the end of the nipple to open and close the same, a yieldable post on which the valve is oscillatably mounted, means for oscillating the valve, a link pivotally connected to the valve, a rod to which the link is pivotally connected, a guide through whichthe rod is slidable, an abutment on the said rod, and

a spring encircling the rod'interposed between the guide and the abutment.
